cracks in rendering

My house has an exterior of plain bricks around the ground floor and white
rendering around the upper floor.
There are a few cracks in the rendering. It could be subsidance I suppose
but I have no problems with the lower brickwork and from what I can see of
the interior uncovered walls there does not seem to be anything too bad.
The rendering cracks seem to get worse in the dry hot summer months with
nothing similar seeming to happen in the winter. Also there are a few
identical houses in my area and I have noticed the odd crack in their
rendering also.
Hopefully assuming it is not something serious like subsidance what can I
do to improve things?
